NIH Study - CWD Prions From Deer Not Transmitted to Humans

Chronic Wasting Disease (CWD) in deer has been a huge concern for those who consume venison.  A recently released study found that the prions associated with CWD in deer did not transfer to humans in laboratory studies.

"In the new CWD study, the bulk of which was done in 2022 and 2023, the research team validated the study model by successfully infecting human cerebral organoids with human CJD prions (positive control). Then, using the same laboratory conditions, they directly exposed healthy human cerebral organoids for seven days with high concentrations of CWD prions from white-tailed deer, mule deer, elk, and normal brain matter (negative control). The researchers then observed the organoids for up to six months, and none became infected with CWD."

"This indicates that even following direct exposure of human central nervous system tissues to CWD prions there is a substantial resistance or barrier to the propagation of infection, according to researchers. The authors acknowledge the limitations of their research, including the possibility that a small number of people may have genetic susceptibility that was not accounted for, and that emergence of new strains with a lesser barrier to infection remains possible. They are optimistic that the inference of these current data is that humans are extremely unlikely to contract a prion disease because of inadvertently eating CWD-infected cervid meat."

"Prion diseases are degenerative diseases found in some mammals. These diseases primarily involve deterioration of the brain but also can affect the eyes and other organs. Disease and death occur when abnormal proteins fold, clump together, recruit other prion proteins to do the same, and eventually destroy the central nervous system. Currently, there are no preventive or therapeutic treatments for prion diseases."

Beethoven's Deafness May Be Result of Lead Poisoning

A study provided insight on how Beethoven may have lost his hearing and suffered other ailments.  A study found high levels of lead as well as high levels of arsenic and mercury through analysis of his hair and this could have accounted for his health conditions.  "For example, one lock contained 380 micrograms of lead per gram of hair, while the second had 258 micrograms per gram of hair. (Normal levels today would be closer to 4 micrograms or less.) His hair also contained 13 times the normal level of arsenic and four times the typical level of mercury."  He also suffered from Hepatitis B which didn't help.

"One theory involves his penchant for wine; he often consumed an entire bottle in a single day. It wasn't uncommon during that time for wine producers to include lead acetate in their concoctions as a preservative and sweetener. Back then, glass bottles also contained traces of lead. The "Fifth Symphony" composer also ate a lot of fish caught in the Danube, which was known for containing arsenic and mercury, CNN reported."

So to what degree did his tortured condition lead him to writing his highly regarded music?

California Bakery Cited for Failure to Comply with Any Regulations

FDA issued a Warning Letter to a California Bakery.  To make the long notice short [I really don't want to type this one out], the firm operated as if they had no knowledge of regulations.  There was no food safety plan, and with that, no controls for allergens, environmental pathogens, etc.  The firm lacked GMPs including pest control, personal hygiene, proper cleaning, etc.  They also had issues with using unapproved color additives and improper labeling.

Canning Firm in China Cited by FDA for Failure to Meet LACF Regulations

FDA issued a Warning Letter to a low acid canned food (LACF) facility, located on Huarong County, Yueyang, Hunan, China. 

• Did not process a food in conformity with at least the scheduled process filed with FDA as required by 21 CFR 108.35 including: products produced in 2023 were processed at a different time and temperature than the scheduled process filed with the FDA
• The heat distribution study does not adequately support the scheduled process filed with the FDA.
• The firm’s retorts did not have an accurate temperature-recording device as required by 21 CFR 113.40(b)(2)
• The processing and production records for products failed to document the specific product variety, approximate number of containers per coding interval, initial product temperature, temperature-indicating device readings, and temperature recording device readings. Additionally, as these USA products are produced in a horizontal still water (b)(4) retort, the firm failed to document time steam on, time temperature up to processing temperature, time steam off, and venting time and temperature to which vented. The abovementioned data is also not documented or recorded on processing and production records for any of the LACF products the firm produces for the USA market.
• The firm did not use or document any form of heat-sensitive indicators or other effective means to ensure the baskets have been processed in the horizontal still water (b)(4) retorts used to process the USA low-acid canned food products.
• The firm’s only printed identification code for  USA hermetically sealed pouches consists of a 10-month best by date, which does not adequately identify the establishment where packed, the product in the container, year packed, day packed, or period during which packed
• The firm did not reference  (b)(4) thermometer to document the retort processing temperature. By the admission of your Equipment & Maintenance Manager, the firm relies on the (b)(4) digital temperature control probe display to document the processing temperatures on the horizontal still water (b)(4) retorts ((b)(4)) used to process LACF products for the USA market.
• The General Manager, Assistant Quality Control Manager, and the Equipment & Maintenance Manager, and none of the processing system or retort operators have ever attended training for thermally processing low-acid canned foods, such as a Better Process Control School, nor are they under the supervision of anyone who has completed such training.

Warning Letter Issued to Spanish Seafood Processor for Inadequate HACCP Plan

The FDA issued a Warning Letter after conducting a Foreign Regulatory Assessment (FRRA) of a  seafood processing facility, located in Sevilla, Spain on October 2 through October 11, 2023. During that assessment, FDA found that the company had serious violations of the seafood Hazard Analysis and Critical Control Point (HACCP) regulation.  This included that the firm’s HACCP plan for green olives stuffed with anchovy or tuna did not list the food safety hazard of scombrotoxin (histamine) formation, Staphylococcus aureus (S. aureus) growth and toxin formation, and allergens associated with the tuna and anchovies; and the food safety hazard of S. aureus growth and toxin formation associated with the olives cooked and fermented at your facility.

FDA Warning Letter to Foreign Supplier Highlights the Need for Supplier Preventive Controls

FDA issued a Warning Letter to a Chinese manufacture of RTE soy protein isolate.  FDA inspected the food manufacturing facility, located in Ye County, Pingdingshan, Henan, 467200, China from August 15 to 17, 2023. Soy protein isolate is used as a protein source in a number of food items including as an ingredient in smoothie mixes, pancake mixes, and breakfast ceral.

This is a great demonstration for the need of a tight Supplier Preventive Control as part of the Preventive Controls for Human Foods OR as part of a FSVP.  Note the issue with Certificates of Analysis (COAs).   A good reason to always verify COA with one's own testing.  This is especially important since this is considered a RTE ingredient.

Issues included:

• 'The hazard analysis covering the RTE Soy Protein Isolate did not identify the hazard of recontamination with environmental pathogens (e.g., Salmonella) as requiring a preventive control.'   
• 'Further, after employees completed and documented cleaning of the packing room, the investigator visually observed apparent soy protein powder residue on food-contact surfaces including the manual hand scoop, powder filling spout, and air removal probes.  The also visually observed soy protein powder residue on food-contact surfaces including the manual hand scoop, powder filling spout, and air removal probes.' 
• 'The production manager also informed the investigator that the only method of sanitization for the equipment in the packaging room is turning on the ceiling-mounted ultraviolet light for (b)(4) minutes before starting packaging. Of course, the company must ensure that the sanitization system is effective in reducing environmental pathogens on food-contact packaging surfaces to a safe level (including those far from the light source, those where the light might not reach, and those with organic residues.)'
• The firm did not take effective measures to exclude pests from the processing, packing, and holding areas and to protect against the contamination of food on the premises by pests, including a live insect was observed crawling inside the facility’s post-heat treatment packaging room for the RTE soy protein products; three live crawling insects and two dead insects were observed on the floor of the spray dryer room, which is directly adjacent and connected to the post-heat treatment packaging room; and a gap was observed at the bottom of the packaging room entry doors.
• Failed to properly store equipment, remove litter and waste, and cut weeds and grass within the immediate vicinity of the plant thus constituting an attractant, breeding place, or harborage for pests, as required by 21 CFR 117.20(a)(1). Specifically, the exterior ground along the south side of the facility was overgrown with weeds and being used as a storage area for scrap metal and old equipment. This area is directly outside the soy packaging room.
• The firm provided the investigator with certificates of analysis (COAs) for outgoing shipments of Soy Protein Isolate to U.S. customers which included results for Salmonella and E. coli testing. However, the firm had no original testing data to support the results on the COA. According to the Laboratory Manager and Food Safety Plan Systems manager, the firm sends their U.S. customers COAs with data that is not supported by actual results but creates the COA with values to satisfy the customer specifications. The firm then performs testing after the batches are sent to the U.S.; however, the testing does not include Salmonella or E. coli.

Washington State Firm Recalls Goat Milk Infant Formula Kit After Adverse Event in Infant

Healthwest Minerals, Inc. d/b/a Mt. Capra Products of Chehalis, Washington, is recalling 1,506 boxes of Goat Milk Formula Recipe Kit on the recommendation of the Food and Drug Administration (FDA) and advises consumers to immediately discontinue use of the product as infant formula. The FDA is concerned that the formula does not meet all FDA requirements for infant formula, does not provide sufficient nutrition when used as an infant formula, and the storage instructions may be insufficient for the product. Infants consuming the recalled product without additional iron supplementation can develop iron deficiency anemia and feeding intolerance.

FDA notified Mt. Capra of an adverse event report of anemia in one infant. FDA determined that while the caregivers were using the Goat Milk Formula Recipe Kit and recipe, the caregivers substituted some ingredients with a different brand of multivitamin, which created a product deficient in vitamin B12 as well as folate and ultimately resulted in the development of anemia.

Japan - Rat Parts Found in Bread

In Japan, a major food company issued a recall for over 100,000 packs of sliced white bread after rat parts were found in the product.  In a statement on Wednesday, Pasco Shikishima Corporation said it was investigating how parts of “a small animal” [a rat] found its way into two packets of sliced bread, adding that no one has fallen sick so far after consuming the product."  "They were found in a batch of white “chojuku” bread — or super fermented bread, known for its extra chewy texture — manufactured by a factory based in western Tokyo prefecture, according to the company."

Perhaps a name change is in order....ratachewy.

Chocolate Covered Potato Chips Recalled Due to Inadvertent Addition of Hazelnuts

Chuao Chocolatier, a Carlsburg, CA firm, is voluntarily recalling a single production of Potato Chip mini bar .39oz/11 gram LOT 4022 because some packages may contain undeclared hazelnut.  The recall was initiated after it was discovered hazelnuts were inadvertently added to the product during manufacturing and the lot produced was distributed in packaging that does not reveal the presence of hazelnuts. Subsequent investigation indicates the problem was caused by cross contamination on a piece of share equipment.

Onion Rings Recalled for Potential Staphylococcus Aureus

In the FDA Enforcement Reports, a recall of fried onion rings due to the potential growth of Staphylococcus aureus.  While the information on the Enforcement Reports is limited, one would guess that the issue was related to temperature control of the batter during manufacturing.  If this is the case, teh concern would be that Staphylococcus aureus may have grown, produced toxin, and now that toxin would be heat stable.  Another possibility was that there could have been a high staph count on the finished product, and if the consumer temperature abused the product, Staphylococcus would grow.

FDA Publishes Final Rule for Use of Agricultural Water on FSMA Covered Produce

FDA released their final rule on agricultural water for produce. "Farms are required to conduct assessments of their pre-harvest agricultural water annually, and whenever a significant change occurs, to identify any conditions likely to introduce known or reasonably foreseeable hazards into or onto covered produce or food contact surfaces."   The rule provides the various factors that go into the evaluation.  

 "The final rule replaces certain pre-harvest agricultural water requirements for covered produce (other than sprouts) in the 2015 produce safety rule with requirements for systems-based agricultural water assessments to determine and guide appropriate measures to minimize potential risks associated with pre-harvest agricultural water."  It "establishes requirements for agricultural water assessments that evaluate a variety of factors that are key determinants of contamination risks associated with pre-harvest agricultural water. This includes an evaluation of the water system, water use practices, crop characteristics, environmental conditions, potential impacts on water from adjacent and nearby land, and other relevant factors."
